Help with a homebuilt & "double dash" code please!

Alright I'll start with system specs:

Intel E6750 Core 2 Duo
EVGA 680i SLI (A1)
4gb Corsair RAM
320 gb WD SE hd
HP DVD+-RW
Crappy case
Purepower TMV 500w PSU


And now for the problem...I bought the parts off a guy that everything working and was using it daily (saw running pics). Once I got the parts I built the whole thing and started it up ready to rock...and that's where the fun started.

The first problem was that it wouldn't see any hard drives connected to it. Whether it be an IDE or SATA. Never loaded Windows, nothing.
After playing with that for a few days and buying the new SATA WD it decided it wouldn't post anymore. I got the "double dash" code.

Googled it and found it might be a grounding problem. Tried it outside of the case, same thing. Next is a bad MB. RMAd it with EVGA and got a new one. Same problem.

Then I tried a newer/better PSU. Nope, not it.

The last thing tech support came up with is it being the CPU, just got my RMA today and it's doing the same thing still!

I've checked grounding problems, bad video card (tried a different one), different RAM in different slots, resetting the CMOS and checking it's battery...everything!!

I'm at my wits end and need help...anyone have any ideas??

Thanks a bunch!
 
If it does it outside the case, I have no idea--that was my first guess until I went back and reread.

Have you swapped out all the cables? Tried running it with only a single hard drive? I've rarely seen bad opticals give out a similar error.

Sounds like you have a beast.

Click to expand...

Memtest? It might be a memory issue, and that seems to be the only thing that you haven't tried.
 
Got my new motherboard...everything works great now! Left bad feedback with EVGA for shipping me a bad MB and then taking forever with the 2nd one.

Thanks everyone!
